UKCAA Part 21J approved design organisation
In-house mechanical and electrical engineering design and drafting services

SWS provide in-house mechanical and electrical engineering design and drafting services, supporting both internal programmes and independent client projects, from simple aircraft modifications to complete cabin reconfigurations.
We work with leading design houses such as Solis Design, factorydesign, JPA and Priestman Goode to offer a combined conceptual design and certification service for cabin interior programmes across large and small aircraft and rotorcraft markets.
By considering certification and airworthiness requirements from the earliest design stages, we help identify key risks early, keeping projects on budget and on schedule without costly surprises later.
The expertise and knowledge of SWS Certification Services has assisted Thompson Aero Seating to gain ETSO and UK TSO's approval for our Vantage seats, as well as providing follow up data to enable seat installations via STC. They are fully worthy of their reputation for competence and quality of service.
